Abstract
This invention is a polymer containing a plurality of ketone groups in the polymer backbone and containing an amount of a non-volatile, ionizable metal salt sufficient to render it static dissipative. The polymer is substantially devoid of a fatty acid salt, a C.sub.6 -C.sub.30 carboxylic acid ester and a phosphate ester compound. The static dissipative polymer can be used neat or blended with other polymers for use in applications requiring static dissipative behavior.
